To all whom it met concern;

Bel'h known that I, LOUIS 1'1, Marian, a CILIZBll-Of-tllfiUnited-,States residing at Lalte;iPai'lc, in ;the county of, Dickinsonand State of Iowa, have invented certain new and nsetulimprovements inExplosive-Engines; j and.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates a base, upon which is supported a horizontally disposedcylinder 6, having the usual Water jacket providing the water chamber 7.A piston 8 is reciproeably mounted in the cylinder 6 and is connectedwith a piston rod 9, to which is attached a cross head 10, slidablysupported in guides 11 positioned upon the base 5. A connecting rod 12is connected with the cross head 10 and with the crank pin 13 of thecrank shaft 14. which latter is supported in suitable bearings mountedupon the base 5 at the end of the latter opposite the cylinder 6. Flywheels 15 are preferably secured to the crank shaft 14-.

A compressor cylinder 16 is formed intogral with the engine cylinder 6,and is also provided with a Water chamber 17 commu- Specification ofLetters Patent.

nici-uing with the water chamber of thecylindcr (i, whereby-tho waterli(:\t(:(l l)y.i ll( engine cylinder during operation of thelattor isconducted to the chamber about the unnprrssor v \linder, so as toell'ectively heat the {tXilltJhltL"HliXillI't prior to its admisltiil tothe explosion chamber-oi the engine. pislon 18 is irciproe-ihlv mountedin the roingin'css'or cylinder lt'i andiis pivotally conlit 1ll0(l;\lilla connecting rod 19, which latter is attached at its opposite extremityto a crank pin L' l, rarried by theengine-shaft l l. whereby thecompressor is operated during operation of the engine. Theorank\\':tltll with relation to the direction of rotation either-rank shaft1.4, of the crank pin 13 .of the engine. so that-the compression oftheexplosive;chargcrin the com:

pression cylinder reaches its maximum prior to the termination of thecompression stroke of theengiue piston 8.

The. head of the compression cylinder-16 is formed with an inlet port,'21. which is i connected with a-carlmreter. mot-showmand thezpassagc oithe gaseous fuel to the inte rior of the cylinder is controlled by aniiiwardly opening valve which is automatically actuated by the suctioncreated in the cylinder during the receding stroke of the piston 18. Thehead of the cylinder 16 is also provided with an outlet portcommunicatinr with the passage 23, which connects the interior of thecylinder 16 with the interior of the engine cylinder (5, and the passageof the explosive mixture from the interior of the cylinder 16 to thepassage 23 is controlled by an inwardly opening valve 23.

The head of the engine cylinder 0 is provided with an exhaust port "24.and the passage of the products of combustion from the explosion chamberof the cylinder 6 through the port 24 is controlled by an inwardlyopening exhaust valve The port connecting the passage 23 with theexplosion chamber of the engine cylinder 6 is controlled by an inwnrdl)opening inlet valve 26. The alves and 20 are preferably of the springclosed type and are nieclninically opened by rocker arms 27 andrespecly. the rocker arm 37 being actuated by a ram '35) engaged with apush rod 28, and the rocker nrni 3'2 living actuated by a push rod '29engaging a cam 30. A pivoted rocker arm 31 is also engaged with theexlmusl valu- 215" of the compressor cylinder J0 and lhe rocker arm 31is engaged with the push rod 29, whereby the inlet valve 26 of thecylinder and the exhaust valve 23 of the compressor cylinder aresimultaneously opened.

In operation, the explosive char e is drawn through the inlet passage 21an into the compressor cylinder 16 during the re ceding stroke of thepiston 18, which, as before stated, travels in advance of the enginepiston 8. During the subsequent instroke of the piston 18 the inletvalve 22 is auton'iatically closed and the explosive mixture in thecylinder 16 is compressed, and as the piston approaches the limit of itsin ward movement the valves 23 and 26 are automatically opened by thecam {50 and push rod 29, thus permitting the highly compressed charge toenter the explosion chamber of the cylinder 6 through the passageSubsequent to the admission of the explosive mixture to the interior ofthe cylinder 6 the valves 23 and 26 automatically close, and during thecontinued inward or compression stroke of the engine piston 8 themixture is compressed to a still higher degree and is finally ignited bya suitable ignition device (not shown). Subsequent to the explosion andexpansion of the mixture the exhaust valve 25 is automatically opened bythe rocker arm 27, push rod 28 and cam "39 and the producls ofcombustion are conducted from the cylinder through the passage 24.

What 1 claim is:

1. In an explosive engine, an engine cylinder, a compressor cylinder,pistons reciprocably mounted in said cylinders, said cylinders having apassage therein connecting them valves for controlling the passage ofgaseous fuel through said passage, angularly disposed rocker armsengaging said valves, and a push rod engaging the converging terminalsof the rocker arms simultaneously actuating said valves.

2. In an explosive engine, an engine cylinder, a compressor cylinder,pistons reciprd cablv mounted in said cylinders. said cylin- (lershaving a passage connecting the interiors thereof, inwardly openingvalves arranged in the ends of the cylinders for controlling the passageof gaseous fuel through the passage, a reciprocable push rod, andpivoted rocker arms engaging said valves and arranged to be actuated bythe push rod simultaneously opening said valves.

In testimony whereof I afiix my signature in presence of two witnesses.
